I bought a Crown Graphic today, and when I got home to try it out, I realized that the film holders I have do not fit. They are too big! I've had the film holders (riteway) a long time and I assumed they would work with all 4x5 cameras.

Just by looking at the back I thought it was the standard Graflok, but after some research it looks like there's a chance it is in fact a Graflex. I read that the Graflex back requires different sized film holders.

I also gather there was a 3 1/4 x 4 1/4 version of the Crown Graphic. I am 99% sure mine is a 4x5 (the 1% uncertainty coming from me second-guessing myself now) but I am hoping you guys can give me some input based on these pictures.

My fingers are crossed I did not mistakenly purchase the strange 3 1/4 x 4 1/4 version... :-/ I would feel really dumb.

Based on that photo of the holder part way into the Graflok back, I'm 99% sure that you did in fact buy a 3 1/4" x 4 1/4" Crown. As Dan says to be absolutely certain refer to the serial number lists, or measure the film gate.

Where can I find the serial number lists? And would measuring the ground glass be the same measurement as the film gate? I'm not sure what the film gate is. Or at least, I know what it is but I don't know what it's called!

The dimensions of the glass: 4 1/8 x 3 1/8.

Probably a dumb question but... I was looking on eBay and some people are selling 4x5 Graflok backs, I don't suppose I could simply buy a different back and put it on?

http://www.freestylephoto.biz/ has Efke in 3 1/4x4 1/4.
Graflex made roll film holders for 3x4 cameras. The Graflex version will work with Graflex or Graflok backs, the Graphic version works with Graflok backs only. An adapter plate can easily be made to attach 2x3 roll film backs to the 3x4 graflok back you have also. 4x5 RFH cannot be cut down to fit._________________The best camera ever made is the one that YOU enjoy using and produces the image quality that satifies YOU.

hey
how much did you pay for it & can you take it back??
I have been looking for a 3 1/4 x 4 1/4 version of the Crown Graphic.
to put with my 4x5 & my 2x3
if the price is not to bad I would look at buying
